             Summary: GenericUDTFGetSplits should support ACID reads in the temp. table read path
                 Key: HIVE-19808
                 URL: https://issues.apache.org/jira/browse/HIVE-19808
             Project: Hive
          Issue Type: Bug
            Reporter: Eric Wohlstadter
            Assignee: Eric Wohlstadter


1. Map-only reads work on ACID tables.
2. Temp. table reads (for multi-vertex queries) work on non-ACID tables.
3. But temp. table reads don't work on ACID tables.
